This image of the core of galaxy M100 shows faint structure as small as 30 light-years across in a galaxy tens of millions of light-years away, made possible by The Hubble Space Telescope's improved optics.
NASA's Hubble Space Telescope discovered new protoplanetary disks around newly formed stars in this 1992 photo.
This 2005 photo from the Hubble shows the Whirlpool Galaxy, M51, seen with unprecedented clarity. At the time, this was one of the largest Hubble images released.
This image of a supernova remnant was produced in 2000 to commemorate the space telescope's 10th anniversary.
This composite image of the active galaxy M82 was taken from infrared observations in three wavelength bands coded in red (longest wavelength), green, and blue (shortest wavelengths).
Resembling curling flames from a campfire, this magnificent nebula in a neighboring galaxy is giving astronomers new insight into the fierce birth of stars as it may have more commonly happened in the early universe. The glowing gas cloud, called Hubble-V, has a diameter of about 200 light-years.
The sharpest image ever taken of the large 'grand design' spiral galaxy M81 is was released at the American Astronomical Society Meeting in Honolulu, Hawaii. A spiral-shaped system of stars, dust, and gas clouds, the galaxy's arms wind all the way down into the nucleus.
Previously unseen details of a mysterious, complex structure within the Carina Nebula are revealed by this image of the 'Keyhole Nebula,' obtained with NASA's Hubble Space Telescope in 1999.
The Hubble Space Telescope hovers at the boundary of Earth and space in this picture, taken after Hubble's second servicing mission in 1997. Hubble drifts 353 miles above the Earth's surface, where it can avoid the atmosphere and clearly see objects in space.
The brilliant stars seen in this image are members of the popular open star cluster known as the Pleiades, or Seven Sisters. The Hubble Space Telescope's Fine Guidance Sensors refined the distance to the Pleiades at about 440 light-years. The Fine Guidance Sensors are at the periphery of Hubble's field-of-view. They trace a circumference that is approximately the angular size of the Moon on the sky. They are overlaid on this image to give a scale to Hubble's very narrow view on the heavens.
Astronaut Steven Smith took this picture of fellow crew member Mark Lee during Hubble's second servicing mission in 1997. Lee is preparing to document the day's activities with a shuttle camera. Engineers rely on astronauts' photos to design and build new hardware for Hubble, and other astronauts use them for training. In addition to the hand-held cameras, the shuttle has cameras mounted to it in various locations to capture other footage.
This image shows a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth — and death — is taking place. This image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble's Advanced Camera for Surveys.
Thousands of sparkling young stars are nestled within the giant nebula NGC 3603. This stellar 'jewel box' is one of the most massive young star clusters in the Milky Way Galaxy. NGC 3603 is a prominent star-forming region in the Carina spiral arm of the Milky Way, about 20,000 light-years away.
NASA's Hubble Space Telescope photographed three magnificent sections of the Veil Nebula -- the shattered remains of a supernova that exploded thousands of years ago. This series of images provides beautifully detailed views of the delicate, wispy structure resulting from this cosmic explosion.
This view of Jupiter and its moon Io was taken by the Hubble telescope.
The Hubble telescope observed the fire and fury of a stellar birth in this photo of a Herbig–Haro object, a gigantic patch of nebulosity associated with newly born stars.
Hubble's observation of the Horsehead Nebula, a dark nebula approximately 1,500 light years from Earth is seen in this photo.

Long considered a planet, Pluto was reclassified as a 'dwarf planet' in 2006 by the International Astronomical Union. Will the discovery of a fifth moon prompt astronomers to reconsider?
Scientists on Wednesday (July 11) announced the discovery of a fifth moon orbiting Pluto in a major solar system find. But while many people think of moons as accessories for planets, like the Earth's moon or Jupiter's many moons, Pluto doesn't quite make the cut in the International Astronomical Union's (IAU) definition of "planet."
